How do I use this. Is there an issue with the tool kit that is on Appcelerator market place? I am not able to successfully use that took kit so far. It is always dumping the message "Authentication needed" and never shows the login screen from SF.

use this like:

var FDC = require('com.salesforce');  
Ti.include('fdc-patch.js');  
FDC.ForceOAuth2.open('CLIENT_ID', 'CLIENT_SECRET');  

as far as I tested, the original toolkit does not handle "refresh token" properly, and ends up with logging 401 error messages.. :(

Thank you for the quick reply. I am still having issues with this thing. Below is the code that I am using with Dev Account in SF:

FDC = require('com.salesforce');
Ti.include('fdc-patch.js');
FDC.ForceOAuth2.open('3MVG9y6x0357HlefBtivwCfw64JZbW5NOvYNkQXcHY9H38fLihuJiCAE6mHuuZdzftJ_L_tuMhg==', '7990050930547381579');

FDC.ForceOAuth2.query("select id, name, billingCity, billlingState from Account", function(e) {
for (var i=0; i < e.records.length; i++)
{
tableData.push( Ti.UI.createTableViewRow({title:e.records[i].name}));
}
}, function(e) {
Ti.API.debug(e);
});

var tableview = Titanium.UI.createTableView({
    data:tableData
});

And here is Error Out put that I get:

Hope you can shed some light on to this.

Thanks,

sorry, i forgot to mention that you need to use "makeRestCall" method directly.
like:

FDC.ForceOAuth2.makeRestCall('/data/v22.0/query/?...', function(e) {...});

client_secret no more needed for refresh.
